A) It's a foot compared to historical levels, it's 10cm since the 1990s.
B) It's a constant problem in Miami where high tide is now above the level of many roads so they've had to jack the roads up several feet more.
C) Venice, Italy is routinely flooded because of sea-level rise and it's only getting worse.
- singularity2001 8y agook 30 cm is a lot. one thing that I don't fully understand yet: there were always storm surges above 2m (?) how come that 50cm sea-rise without any storm surges are already causing problems?
- mikeash 8y agoAn extreme event that happened once every few years (or decades) might be tolerable, and become a vastly larger problem if it starts happening once a month instead. New York recovered from Sandy, but the city would need massive changes if that water level became routine.
- astrodust 8y agoHaving a higher base-line sea level is never going to help with flooding. Remember a component of the rise is that the water is warmer, and warmer water takes up slightly more space, but the real problem is that the increased temperature makes storms more aggressive and from there increases storm surge.
- vonmoltke 8y ago> B) It's a constant problem in Miami where high tide is now above the level of many roads so they've had to jack the roads up several feet more. No, it isn't. It's a problem during king tides. Yes, king tide flooding is getting worse, but "constant problem" is an exaggeration.
- singularity2001 8y agothanks for the clarification. anything except exaggerated tides wouldn't make any sense to me
- astrodust 8y agoWhen parts of your city flood every king tide that's a constant problem because that threat has not gone away.
